When should you let a wine breathe?

‘I always give the same advice to people,’ said Robert. ‘It is important to have researched the wine; to know the character of the wine and how it should taste.

‘If you were, for example, in the presence of a fragile wine, like an old vintage bottle, then I would not risk aerating it too much. I would probably open it in advance and try to find the right type of glass.’

‘Personally, I would recommend a Bordeaux glass rather than pouring it in to a decanter.’
